Description

The objective of this videotape is to stress the importance of uninterruptible power supplies for protection and control circuits, and to look at different means of achieving this. The provision of both continuous AC and continuous DC power supply is discussed and attention is paid to individual power supplies for electronic equipment. Some time is devoted to studying operation and maintenance of the common storage battery. This area often seems to be neglected, even though it is after all, the heart of uninterruptible power supplies. After study of this tape and the associated workbook participants should be able to understand the following overall concepts, and apply them in their day-to-day work activities. They will also be able to answer related test questions on these subjects: The need for 'reliable' continuous power supplies to operate protection and control relays and circuits. Different voltage level requirements, The lead acid cell; lead antimony; lead calcium, Connection of cells in series to form a storage battery, Ampere hour rating, Battery charge rate, overcharging, Hydrogen release, Significance of specific gravity and output voltage per cell, Equalization procedure, Sulfation, Safety precautions against acid, The nickel cadmium cell, Supply to the DC bus, The SCR battery charger, Control of SCR firing, DC output filter circuit, Charger adjustments: float voltage, equalization voltage, programmed equalization, output slope, and current limiter, The controlled ferroresonant battery charger, The need for uninterruptible AC power supply, The DC to AC inverter, Pulse generation and pulse width modulation, The off-line UPS system, The on-line UPS system, The reverse transfer UPS, The triport UPS system, Power supplies for electronic equipment, The need for clean DC power, The need to shield connecting leads, The transformer rectifier circuit, Features of the filter capacitor, Regulation of DC voltage supply, The series pass transistor regulator, Interference from VHF radios, The switching transistor voltage regulator.

If you are taking this course for NERC credit, the following credits will be reported.
